Abstract

Fecal nematode egg counts and serum pepsinogen concentrations of cattle were determined in six Provinces of the northern (Chiangrai and Lampang), north-eastern (Khonkaen, Mahasarakham and Nakhonratchasima) and eastern (Chonburi) parts of Thailand in the dry season. Nematode eggs were detected in 82% of animals examined. Serum pepsinogen concentrations ranged from 78 to 2,951 (mean 934) mU tyrosine. Animals in Chonburi Province had higher mean values for both egg counts and serum pepsinogen concentrations than animals in the other Provinces. Two calves in Khonkaen and Mahasarakham Provinces were found to be heavily infected with Strongyloides papillosus, with 10,840 and 9,593 eggs/g feces. The source and route of S. papillosus infections remained unknown.
